FIELD: consumer harmonic emission identifying.
SUBSTANCE: invention is intended to identify the harmonic emission of the consumer, namely, to determine the time-varying actual contribution of the consumer to the overall level of non-sinusoidality of the network voltage for individual harmonics for the considered time interval. The substance of the invention lies in the fact that the actual contribution of the consumer to the overall level of non-sinusoidality of the network voltage at the frequency of individual harmonics is determined based on the response of the network under study to the input broadband measuring interference, while generating and repeatedly introducing a signal of a ternary pulse sequence into the network, measuring the voltage at the connection point and currents of the consumer and the network, determining the spectral components of the voltage at the connection point and the currents of the consumer and interference, calculating the time-varying amplitude-frequency characteristics of the resistance of the network and the consumer, calculating the time-varying actual contributions of the consumer and the network.
EFFECT: increasing the reliability of determining non-stationary levels of the actual contribution of the consumer to the non-sinusoidal voltage at an arbitrary point in time.
